Variations in climate conditions can dramatically affect plant health and the generation of climate-resilient crops is imperative to food security. In addition to directly affecting plants, it is predicted that more severe climate conditions will also result in greater biotic stresses. Recent studies have identified climate-sensitive molecular pathways that can result in plants being more susceptible to infection under unfavorable conditions. Here, we review how expected changes in climate will impact plant-pathogen interactions, with a focus on mechanisms regulating plant immunity and microbial virulence strategies. We highlight the complex interactions between abiotic and biotic stresses with the goal of identifying components and/or pathways that are promising targets for genetic engineering to enhance adaptation and strengthen resilience in dynamically changing environments.
气候变化会显著影响植物的健康，培育具有气候适应能力的作物对于粮食安全至关重要。除了直接影响植物外，预计更恶劣的气候条件还将导致更大的生物胁迫。最近的研究已经确定了一些对气候敏感的分子途径，这些途径可能导致植物在不利条件下更容易受到感染。在这里，我们综述了气候变化预期将如何影响植物-病原体相互作用，重点关注调节植物免疫和微生物毒力策略的机制。我们强调了非生物和生物胁迫之间的复杂相互作用，目的是确定有希望成为遗传工程目标的成分和/或途径，以增强在动态变化环境中的适应能力和韧性。
